Overview
MICROCIRCUIT DATA SHEET MNLM129A-X REV 0CL PRECISION REFERENCE General Description The LM129 is a precision multi-current temperature-compensated 6.
9V zener reference with dynamic impedances a factor of 10 to 100 less than discrete diodes.
Constructed in a single silicon chip, the LM129 uses active circuitry to buffer the internal zener allowing the device to operate over a 0.
5 mA to 15 mA range with virtually no change in performance.
The LM129 is available with selected temperature coefficients of 0.
001, 0.
002, 0.
005 and 0.
01%/ C.
These new references also have excellent long term stability and low noise.
A new subsurface breakdown zener used in the LM129 gives lower noise and better long-...
